Raiders sign former Buc; minicamp update

The Raiders agreed to terms with free-agent defensive end Greg Spires, an NFL source said Saturday.

He’s a 10-year veteran who started five of the past six seasons with the Buccaneers, including their Super Bowl XXXVII victory over the Raiders in 2002.

Spires missed six games last season with a calf injury. He’s considered undersized for the position at 6-foot-1, but has used above-average speed to pick up 39.5 career sacks.

In a perfect world, Spires will have enough in the tank to complement left end Derrick Burgessjust as he did Simeon Rice in Tampa Bay. Worst-case, he’ll make defensive ends like Jay Richardson and Kalimba Edwardsearn their roster spot.

The Raiders have hoped to find a veteran free agent (without spending a ton) to replace free-agent departure Chris Clemons, who had eight sacks last year.
